Error: avalon_slave: Agent with readdatavalid signal must support at least 1 pending read

Hi Kenny

the quartus tool is in our EC machines and screenshots are disabled for security and IP compliance policies. I wont be able to share screenshot. Here are some feedback which may help you with what you may be looking for.

1. i created my custom IP in platform designed using "new component" on top left of the gui
2. i added AVMM Memory agent port and signal to my design. I saved and close the component.
3. I used this component in my platform designer gui and made connections as desired.
4. I tried to do generated HDL and it failed with the error i reported.
5. from error I could figure out that it has to do with AVMM agent port and missing parameter.
6. in Platform designer i clicked on my component , on right top corner of the window , i chose component instantiation.
7. Now here on top right area of Platform Architect Gui, I felt that things are cramped here and and because of GUI theme colors (same shade of grey) i think i missed a thin horizontal bar initially, which would indicate that there things to your right.
8. Once I (accidently) figured that out i was able to see all parameters field there.

i hope this helps
